Preface
The time goes back to 2006, ROG, one of the brands of ASUS , was born. I believe that digital enthusiasts have different needs for the ultimate performance and cool appearance of the product, which is a great choice for overclocking enthusiasts and game enthusiasts. The parties bring top solutions for extreme applications.
Today, ROG Gamers already has multiple digital product lines such as motherboards, graphics cards, notebooks, monitors, chargers, etc. Although the price is very expensive for ordinary users, the performance adjustment has to be said to be very excellent. Recently, Charging Head Network got a ROG 100W fast charging charger. Does it continue its consistent extreme performance tuning? Next, the charging head network will conduct actual measurement and answer.

The charger output power is 15.04V 0.31A 4.79W, and the base TV mode is successfully lit. summarized the compatibility test data. Overall, whether it is a mobile phone, a game console, a tablet, or a laptop, fast charging can be triggered. The 100W fast charging power can also meet the fast charging needs of laptops. In the histogram part, the notebook computer naturally has the highest power, and the power histograms of other devices decrease in sequence. Because ROG’s charger supports 100W output power, I chose to charge the MacBook Pro 16 2021 this time to maximize the performance of the charger. This is the data of the entire charging process of MacBook Pro 16 2021 using ROG 100W charger. The whole process is roughly divided into 4 stages. Charging ends in 2 hours and 4 minutes. The maximum power is 19.8V 4.53A 89.81W. draws the entire charging process into a curve chart. As can be seen from the curve chart, the charger charges the MacBook Pro 16 2021 41% in half an hour and 78% in 1 hour. It takes about 2 hours and 4 minutes to fully charge. Nowadays, it has become normal for users to not unplug the device from the socket after using the charger to charge the device. Many readers want to know whether the charger wastes electricity if it is always plugged into the socket. The standby power consumption test session is to answer this question. has been tested by power meter . The no-load power consumption of the charger at 220V 50Hz is 0.125W. The converted power loss in one year is about 1.09KW·h. If the market price of electricity is 0.6 yuan/KW·h, the charger The annual electricity bill is about 0.654 yuan. The no-load power consumption of Preface

Standby power consumption test
10V at 60Hz is 0.047W. After conversion, the electric energy lost in one year is about 0.41KW·h. If the market price is 0.6 yuan/KW·h, the annual electricity bill of the charger is about 0.246 yuan.
Summary
The standby power consumption test is how much power will be consumed in a year if the charger is plugged into the socket and not used. As for the numerical value, the lower the better. First of all, after the above test, the standby power consumption of the ROG 100W charger is completely less than the specified value of GB20943-2017 standard which should not be higher than 0.5W.
Let’s calculate the money on the premise of meeting the standards. According to actual measurements, when the ROG 100W charger is not used in the socket in a 220V mains power environment, the electricity bill used in a year is only about 60 cents; and in a 110V mains power environment No, the electricity bill used in a year is only about 20 cents. It's almost negligible.
Conversion efficiency test
The charger is essentially a conversion device, and there will be losses in the process, which are emitted in the form of heat. We usually look at the parameters on the charger. The output of 100W or 65W is the maximum output power that the charger can provide for the device, but the power the charger draws from the socket is often larger. The following is the charger's AC 220V 50Hz and 110V 60Hz Conversion efficiency tests were conducted separately under the input conditions, and the test results are as follows.
20V 50Hz, test the charger at full output power at each voltage range: the input power at the AC end of the power strip and the output power at the USB end are measured at the four levels. Through calculation, the conversion efficiency of the charger can be obtained from It ranges from 84.84% to 89.61%.
10V 60Hz, the charger's conversion efficiency ranges from 85.4% to 88.75%.
Summary
The conversion efficiency can reflect the quality of the charger. From the data point of view, the higher the percentage, the better. It can be seen from the above test data that the efficiency at high power output is mostly above 89%. The high-power fast charging of the Lenovo charger is aimed at charging laptops. The most intuitive feeling for users is that charging laptops is efficient and the heat generation is naturally low.
Ripple test
Since the charger uses switching power supply , the secondary output of the transformer is not direct current . It needs to be output through rectification and capacitor filtering, that is, there will be ripples in the charger output. Charging Head Network uses oscilloscope to test the ripple value output by the charger, compare it with national standards, and detect the output quality of the charger.The lower the ripple, the higher the quality of the charger's output.
ripple test is divided into two types: no-load (the Y-axis current in the histogram is 0A) and heavy load (the Y-axis current in the histogram is non-0A). In the no-load part, under 220V 50Hz AC input, the charger has the highest ripple at 9V0A no-load state, which is 72mVp-p; and the lowest ripple at 20V0A no-load state, which is 48mVp-p. Under 110V 60Hz AC input, the
charger has the highest ripple at 9V0A no-load state, which is 72mVp-p; and the lowest ripple at 20V0A no-load state, which is 48mVp-p. In the heavy-load part of
, under 220V 50Hz AC input, the charger has the highest ripple at 96mVp-p when it is in the 15V2A and 20V5A output states; the lowest ripple is 72mVp-p when it is in the 5V3A output state. Under 110V 60Hz AC input, the
charger has the highest ripple when it is in the 20V5A output state, which is 98mVp-p; when it is in the 5V3A output state, the ripple is the lowest, which is 40mVp-p.
Summary
The lower the ripple value, the higher the output quality of the charger. Judging from the test data, the ripple value of the entire charger is at a low level, indicating that the output quality of the charger is very high.
Temperature test
As mentioned earlier, the problem of efficiency conversion is involved when the charger is working. Most of the power lost is dissipated as heat, so the heat generated by the charger when working for a long time is also an important part of the test. Let the charger continuously output 100W power for one hour, collect the surface temperature of the charger, and place the charger in a 25°C constant temperature box throughout the experiment.
First, let’s take a look at the temperature performance of the charger in a 220V50Hz mains environment.
html After 31 hours, the maximum temperature of the two side surfaces of the charger was photographed using a thermal imager to be 57.9°C.
The maximum temperature of the other two side surfaces is 60.2℃.
Let’s take a look at the temperature performance of the charger in a 110V 60Hz mains power environment.
html After 31 hours, the maximum temperature of the surfaces on both sides of the charger was photographed using a thermal imager to be 59.8°C.
The maximum temperature on the other two sides of the surface is 65.8℃.
summarized the four temperature data tested, and none of the four data exceeded the specified maximum value of 95°C. In the histogram part of
, you can easily see the maximum temperature and the minimum temperature. In the 110V mains power environment, the temperature is higher, 65.8℃; in the 220V mains power environment, the temperature is lower, 57.9℃, which is also completely lower than GB4943. 1-2011 for temperature limits.
